Dell Dimension 8250 PC running Windows XP has CPU always at 100%

I run Windows XP on my system. I formated my HD 4 Times and reinstaled Windows XP 4 different times. My whole system runs slow. I click on a program and it takes 5 min. to boot up. I currently having 100% CPU Usage. I currently have no programs or softawre on my computer. The only things i have is the Drivers that a Dell. Tec. Support agent told me to install. I replaced the Hard Drive and i relaced the Video Card. I also replaced my Wireless PCI card. I don't want to replace the Processor or the MB yet cause that is BIG Bucks. I also Ran the 32-Bit Diognostics test from my Dimension Resource CD. It came back saying that i have no Cache.

Error Code: 0700:0120 No ache Detected. Cache might be defective or not present.

i don't know wha process are using it. Dell doesn't even know. I called Dell but Dell Connect couldn't connect cause i run so slow. I have 512MB of Ram. and i have 2.66 Giga Hertz. I have a 120 GB hard drive and i formatted 3 different ways different times. I formated quick once, formated non-quick once, and i FDISK once when i booted from my Dell Dimension Recource CD. I opened a DOS session and typed in FDISK and manually deleted the partition.i don't know wha process are using it. Dell doesn't even know.

When you reinstalled, did you do a format (not quick)Your CPU is at 100 but what process(es) are using it.
How much RAM do you have.
How big is your hard drive.
When you reinstalled, did you do a format (not quick)

The cache is nothing more than a file on the hard drive, if it is missing Windows automatically creates it. If it was corrupt, formatting would have gotten rid of it. Try booting in safe mode (and afterwards safe mode with networking) to see if you have the same problem. This could also be a hardware issue, remove any cards that have been added (including video, I assume it has an onboard chip) and see if it helps. If any of this helps, it gives us the info to fixed it permanently.

Windows XP needs at least 1 GB of RAM to function reasonably and for best performance, go to 2 GB. But that might not be the main problem. You really need to install the system drivers to make the O/S work with the hardware. Then run the command MSCONFIG from the command line and click the startup tab to see what might be running in the background. Uncheck the things you don't need.

to restore to your pc as it was from the factory you will need the cd's that came with the computer. one of those will be the Operating System cd. Once you have located the correct cd, boot from that cd and follow the instructions to reinstall the operating system.

Sounds like the machine got stuck in the middle of a installation of windows. Best thing to do is to reinstall windows and let the cd format the hard drive, if it can't format the hard drive then the hard drive is bad and would need to be replaced.

The fan settings can be found in the BIOS. On a Dell machine, when you turn the computer on repeatedly hit F2 until you are brought to the BIOS. Search through there until you find something named Acoustics, change the option to run at a lower level. Remember to save the changes before you exit.

The Dimension 8250 was not equipped by Dell with an automated re-image process. If you want a clean installation of Windows, it will require a manual installation from the Dell Windows Media, followed by installing the drivers from either the resource CD or internat download. Once completed, then reinstall all applications.

I guess it could be a virus, avast is not the best antivirus in my opinion, try to get a norton antivirus or NOD32 update it and run the scan, it ocuurs when a replicating virus copies files to all your HDD and is always busy...making system busy...and one more thing there could easily be a copy of the virus in your pen drive as well...
